[X4U] Re: Copying a 5.3 gig DVD image?

[David Checkman]

If I can piggyback on Robert Nicholson's initial request for 
information about how to handle files too large to fit on a single 
DVD ...

(Please, I can do without someone's generic response: "Why would you 
want to burn such a DVD when you could ... (complete the sentence 
yourself)."

To make my own questions more concrete: does anyone know of software 
(I have OSX 3.9) that does either/both of these jobs: 
compresses/splits 9 GBs of files on my HD to DVD size chunks 
preliminary to burning to DVDs?

And, does anyone know of software that will make such DVDs *bootable* 
(wait! ... don't jump to CCC, etc. so fast) so that the DVDs I've 
just burned (see the paragraph above) somehow get re-assembled into a 
single file on my desktop that I will then be able to re-install 
if/when disaster strikes?

Thanks.

Dave
